Research on Coordination Dispatching Strategy of Active Distribution Network and Intermittent Energy

It is a technical difficulty for the safe and economic operation of active distribution network to control and manage distributed generators, distributed energy storage and load flexibly and effectively to eliminate the influence of distributed energy uncertainty on grid. In order to realize the full consumption of a large number of intermittent energy sources in active distribution network, this paper proposes an optimal control strategy for active distribution network considering energy storage system and controllable load. And a multi-objective optimal dispatching model with the lowest active power dispatching cost and the smallest intermittent energy reduction for active distribution network is established. The improved particle swarm optimization algorithm is used to solve the model. Finally, a simulation system is constructed to verify the effectiveness and feasibility of the proposed control strategy.
